For a reversible reaction: 2NO2 ⇌(K1/K2) N2O4, the rate of disappearance of NO2 is equal to — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

The rate of disappearance of NO2 is given by multiplying its stoichiometric coefficient by the net rate of the reaction. Rate = 2 × (Rate_forward - Rate_backward) = 2(K1[NO2]^2 - K2[N2O4]) = 2K1[NO2]^2 - 2K2[N2O4]. Therefore, correct answer is B.
